United States kick-off Olympics in style, Germany dismantle Zimbabwe
Goals from Carli Lloyd and Alex Morgan saw the United States beat New Zealand, while Germany were far too strong for Zimbabwe.
Defending champions the United States kicked-off their Olympic women's football tournament with a win over New Zealand, while Germany put six goals past a hapless Zimbabwe.
USA, winner of gold in London in 2012, started things brightly against New Zealand on Wednesday with a goal inside nine minutes through captain Carli Lloyd.
It took USA just seconds to double their lead in the second half, with Alex Morgan finding the net to wrap up a 2-0 win in Belo Horizonte.
Germany meanwhile scored four second-half goals to seal a 6-1 victory over Zimbabwe, with Melanie Behringer netting a brace for the 2015 Women's World Cup semi-finalists.

Hosts Brazil secured a 3-0 win over China PR, Sweden edged South Africa 1-0 courtesy of Nilla Fischer's 75th minute goal, and France made easy work of Colombia, winning 4-0.
HIGHLIGHT
Australia, ranked fifth in the world, were favourites going into their Group F opener with Canada, but Beckie was on hand to tap home just 20 seconds into the first half for the North Americans following a defensive error, which was the fastest goal in Olympic women's football history.
